利用时幅转换测量光场的二级相干度

The Measurement of the Degree of the Second Order Coherence of Ogtical Field Using the Method of Time-to-Height Convertor

本文研制用时幅转换器测量光子的时间间隔分布的实验装置。在一定条件下这个分布等效于光场的二阶相干度。我们测量了相干光和准高斯光的二阶相干度,结果从原理上证实本实验装置的可靠性。

The experimental apparatus of time-to-height convertor for measuring time-intervalprobablity of photons has been set up. Under certain condition this probablity distribu-tion is equal to the degree of second-order coherence of optical field. The degree of se-cond-order coherence for coherent light and quasi-Gaussian light has been measured,andthe realiability of the experimental method is tested in principle.
